1.5 million views - Put Your Hearts Up (there are several versions of this but here are the views for the top result. Was only uploaded 4 years ago, but the song came out in 2011)

Put Your Hearts Up originally had at least 40 million views but Ariana deleted it from her channel in 2014 (we all know how much she dislikes it!), so all of these versions are just reuploads, which explains the low view count.
